It can not be said that the average grower practices intensive 

 cultivation as it is practiced in some commercial districts. The 

 water supply has been adequate to supplement the normal rainfall, 

 so that there has been no pressing need of conserving moisture. 

 Some growers cultivate their orchards between irrigations, particu- 

 larly after the first. Most orchardists, however, do not cultivate 

 the land after the first irrigation rills have been laid out. For all 

 orchards under all systems of management the average total annual 

 cost for cultivation, including plowung, is $5.52 per acre, or $0.0164 

 per box. (See Table VIII.)

MULCH CROPS. 



The use of mulch crops has become general within the last few 

 years. Only a few orchardists take off more than one crop of hay, 

 and many use the crop entirely for pasture or leave it on the ground, 

 although many others make three cuttings, which may be taken off 

 or left on the ground as a mulch. The most common method of hand- 

 ling mulch crops in this region, however, is to allow hogs to pasture 

 off the crop. In this way the soil is enriched and at the same time 

 the wormy and inferior fruit on the ground is utilized for feed. 



Where mulch crops are grown, it is the practice to go on the land 

 with a disk in the latter part of March or the first of April, The
